Subsequent ones often indicate a downstream component that failed after the first failed. In your case, the 1st error is In file included from src/_tkagg.cpp:18: /Library/Frameworks/Tk.framework/Headers/tk.h:96:29: X11/Xlib.h: No such file or directory So it looks to me that either you haven't installed X11 (which is the default config on OS X) or it's not in your include path. If you haven't installed X11 for OS X, see http://www.apple.com/macosx/features/x11. After you get past this hurdle, you might encounter another road block or two, especially if you are a fink user. In that case, you may want to edit setupext.py and replace the dictionary entry 'darwin' : '/usr/local', with 'darwin' : '/sw', and check out this post http://sourceforge.net/mailarchive/message.php?msg_id=7777103 Good luck!
